Oligarchy is US

When put the numbers to it, it turns out that the US is, in fact, an oligarchy.

 "Despite the seemingly strong empirical support in previous studies for theories of majoritarian democracy, our analyses suggest that majorities of the American public actually have little influence over the policies our government adopts. Americans do enjoy many features central to democratic governance, such as regular elections, freedom of speech and association, and a widespread (if still contested) franchise. But, ..." and then they go on to say, it's not true, and that, "America's claims to being a democratic society are seriously threatened" by the findings in this, the first-ever comprehensive scientific study of the subject, which shows that there is instead "the nearly total failure of 'median voter' and other Majoritarian Electoral Democracy theories [of America]. When the preferences of economic elites and the stands of organized interest groups are controlled for, the preferences of the average American appear to have only a minuscule, near-zero, statistically non-significant impact upon public policy."

So, who is surprised at that finding?
